ST Stepper Motor Control/Driver

<p>The L293D is a monolithic integrated, high voltage, high current, 4-channel driver.</p>

L293E is a quad push-pull driver capable of delivering output currents up to 1A per channel
L297 generates four phase drive signals for two phase bipolar and four phase unipolar stepper motors in microcomputer controlled applications

Device	Function	Package	Order code
L293D	Accepts DTL/TTL logic levels, will drive inductive loads, DC and stepper	DIL-16	82-0192
	motors, switching power transistors.
L293E	TTL compatible control, inhibit input on each pair of drivers, external	DIL-20	82-0194
	connections for sensing resistors.
L297	Motor can be driven in half-step, normal and wave drive modes, on-chip	DIL-20	82-0198
	PWM chopper circuits permit switch-mode control of the current in the
	windings. Requires only clock, direction and mode input signals.
